Look at the following equation: 3H 2 N 2 -> 2 NH 3 If 85.0 gram of N 2 gives 86.2 g of NH 3, what is the percent yie...
2 NH (g) + 3 CuO (s) à Ng) + 3 Cu(s) + 3H,0 (g) Molar Masses NH3: 17.03 Cuo: 79.55 N,: 28.02 H20: 18.02 A) Determine (with a clear supporting calculation) which is the limiting reagent. B) What mass of Cu(s) is formed? C) Only 40.3 g of Cu(s) are recovered. What is the % yield?
Consider the two reactions. 2 NH,(g) + 3 N, O(g) - 4N, (g) + 3H,O(1) 4NH,(g) + 30,(g) — 2N, (g) + 6H, 0(1) AH = -1010 KJ AH = 1531 kJ Using these two reactions, calculate and enter the enthalpy change for the reaction below. N,(g) + 40,(8) NO(g) AH- AHL
